cygwin上编译RPC框架thrift
cygwin的配置就不多说了，缺什么就通过安装器安装好了。
在thrift的官网下载 thrift-0.11.0源码，通过cmake编译，生成Makefile之后，make出现编译错误
/cygdrive/d/work/thrift-0.11.0/mybuild $ make [ 1%] Building CXX object compiler/cpp/CMakeFiles/parse.dir/thrift/thrifty.cc.o /cygdrive/d/work/thrift-0.11.0/compiler/cpp/src/thrift/thrifty.yy: 在函数‘int yyparse()’中: /cygdrive/d/work/thrift-0.11.0/compiler/cpp/src/thrift/thrifty.yy:1197:20: 错误：‘strdup’在此作用域中尚未声明 $$ = strdup("1"); ^~~~ /cygdrive/d/work/thrift-0.11.0/compiler/cpp/src/thrift/thrifty.yy:1197:20: 附注：suggested alternative: ‘strcmp’ $$ = strdup("1"); ^~~~ strcmp make[2]: *** [compiler/cpp/CMakeFiles/parse.dir/build.make:74：compiler/cpp/CMakeFiles/parse.dir/thrift/thrifty.cc.o] 错误 1 make[1]: *** [CMakeFiles/Makefile2:1055：compiler/cpp/CMakeFiles/parse.dir/all] 错误 2 make: *** [Makefile:161：all] 错误 2
查看cmake生成Makefile的日志，在某个cmake文件里设置了-std=c++11，找到：
D:\work\thrift-0.11.0\build\cmake\DefineCMakeDefaults.cmake (2 hits)
Line 79: message(STATUS "Setting C++98 as the default language level (for an older MSVC compiler).")
Line 82: message(STATUS "Setting C++11 as the default language level.")
如下修改：
if (NOT DEFINED CMAKE_CXX_STANDARD) if (MSVC AND MSVC_VERSION LESS 1800) # MSVC 2012 and earlier don't support template aliases so you have to use C++98 set(CMAKE_CXX_STANDARD 98) message(STATUS "Setting C++98 as the default language level (for an older MSVC compiler).") else() #set(CMAKE_CXX_STANDARD 11) # C++11 set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11") message(STATUS "Setting C++11 as the default language level.") endif() message(STATUS "To specify a different C++ language level, set CMAKE_CXX_STANDARD") endif()
继续编译，随即遇到编译错误：
[ 11%] Building CXX object lib/cpp/CMakeFiles/thrift_static.dir/src/thrift/transport/THttpServer.cpp.o /cygdrive/d/work/thrift-0.11.0/lib/cpp/src/thrift/transport/THttpServer.cpp: 在成员函数‘virtual void apache::thrift::transport::THttpServer::parseHeader(char*)’中: /cygdrive/d/work/thrift-0.11.0/lib/cpp/src/thrift/transport/THttpServer.cpp:52:47: 错误：‘strcasestr’在此作用域中尚未声明 #define THRIFT_strcasestr(haystack, needle) strcasestr(haystack, needle) ^ /cygdrive/d/work/thrift-0.11.0/lib/cpp/src/thrift/transport/THttpServer.cpp:64:9: 附注：in expansion of macro ‘THRIFT_strcasestr’ if (THRIFT_strcasestr(value, "chunked") != NULL) { ^~~~~~~~~~~~~~~~~ /cygdrive/d/work/thrift-0.11.0/lib/cpp/src/thrift/transport/THttpServer.cpp:52:47: 附注：suggested alternative: ‘strcasecmp’ #define THRIFT_strcasestr(haystack, needle) strcasestr(haystack, needle) ^ /cygdrive/d/work/thrift-0.11.0/lib/cpp/src/thrift/transport/THttpServer.cpp:64:9: 附注：in expansion of macro ‘THRIFT_strcasestr’ if (THRIFT_strcasestr(value, "chunked") != NULL) { ^~~~~~~~~~~~~~~~~ make[2]: *** [lib/cpp/CMakeFiles/thrift_static.dir/build.make:495：lib/cpp/CMakeFiles/thrift_static.dir/src/thrift/transport/THttpServer.cpp.o] 错误 1 make[1]: *** [CMakeFiles/Makefile2:1140：lib/cpp/CMakeFiles/thrift_static.dir/all] 错误 2 make: *** [Makefile:161：all] 错误 2
这里我就直接修改源代码了：
#define _GNU_SOURCE #include <string.h>
将这两行放在thrift-0.11.0/lib/cpp/src/thrift/transport/THttpServer.cpp的其他include头文件的前面，不然 #define _GNU_SOURCE 会被编译器忽略
随即又遇到编译错误:
/cygdrive/d/work/thrift-0.11.0/lib/cpp/src/thrift/concurrency/Mutex.cpp: 在静态成员函数‘static void apache::thrift::concurrency::Mutex::RECURSIVE_INITIALIZER(void*)’中: /cygdrive/d/work/thrift-0.11.0/lib/cpp/src/thrift/concurrency/Mutex.cpp:271:41: 错误：‘PTHREAD_MUTEX_RECURSIVE_NP’在此作用域中尚未声明 init_with_kind((pthread_mutex_t*)arg, PTHREAD_MUTEX_RECURSIVE_NP); ^~~~~~~~~~~~~~~~~~~~~~~~~~ /cygdrive/d/work/thrift-0.11.0/lib/cpp/src/thrift/concurrency/Mutex.cpp:271:41: 附注：suggested alternative: ‘PTHREAD_MUTEX_RECURSIVE’ init_with_kind((pthread_mutex_t*)arg, PTHREAD_MUTEX_RECURSIVE_NP); ^~~~~~~~~~~~~~~~~~~~~~~~~~ PTHREAD_MUTEX_RECURSIVE make[2]: *** [lib/cpp/CMakeFiles/thrift_static.dir/build.make:951：lib/cpp/CMakeFiles/thrift_static.dir/src/thrift/concurrency/Mutex.cpp.o] 错误 1 make[1]: *** [CMakeFiles/Makefile2:11
这里又是cygwin的库问题了，不支持PTHREAD_MUTEX_RECURSIVE_NP，改成 PTHREAD_MUTEX_RECURSIVE
#ifdef PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP void Mutex::RECURSIVE_INITIALIZER(void* arg) { //init_with_kind((pthread_mutex_t*)arg, PTHREAD_MUTEX_RECURSIVE_NP); init_with_kind((pthread_mutex_t*)arg, PTHREAD_MUTEX_RECURSIVE); } #endif
链接单元测试时又出现库不兼容的问题。。。
CMakeFiles/UnitTests.dir/concurrency/MutexTest.cpp.o:MutexTest.cpp:(.rdata$.refptr._ZN6apache6thrift11concurrency5Mutex20ADAPTIVE_INITIALIZEREPv[.refptr._ZN6apache6thrift11concurrency5Mutex20ADAPTIVE_INITIALIZEREPv]+0x0)：对‘apache::thrift::concurrency::Mutex::ADAPTIVE_INITIALIZER(void*)’未定义的引用 collect2: 错误：ld 返回 1 make[2]: *** [lib/cpp/test/CMakeFiles/UnitTests.dir/build.make:339：bin/UnitTests.exe] 错误 1 make[1]: *** [CMakeFiles/Makefile2:1736：lib/cpp/test/CMakeFiles/UnitTests.dir/all] 错误 2 make: *** [Makefile:161：all] 错误 2
自适应锁在cygwin的最新版是没有的，就给它弄个默认的，该咋死咋死吧：
#ifdef PTHREAD_ADAPTIVE_MUTEX_INITIALIZER_NP void Mutex::ADAPTIVE_INITIALIZER(void* arg) { // From mysql source: mysys/my_thr_init.c // Set mutex type to "fast" a.k.a "adaptive" // // In this case the thread may steal the mutex from some other thread // that is waiting for the same mutex. This will save us some // context switches but may cause a thread to 'starve forever' while // waiting for the mutex (not likely if the code within the mutex is // short). init_with_kind((pthread_mutex_t*)arg, PTHREAD_MUTEX_ADAPTIVE_NP); } #else void Mutex::ADAPTIVE_INITIALIZER(void* arg) { // From mysql source: mysys/my_thr_init.c // Set mutex type to "fast" a.k.a "adaptive" // // In this case the thread may steal the mutex from some other thread // that is waiting for the same mutex. This will save us some // context switches but may cause a thread to 'starve forever' while // waiting for the mutex (not likely if the code within the mutex is // short). init_with_kind((pthread_mutex_t*)arg, PTHREAD_MUTEX_NORMAL); } #endif
OK，至此，完美编译成功！
